[URGENT] What are the failures and successes of solar energy?

may i know what are the examples of failures and successes that are related to solarenergy? need them urgently.. thanks.

admin answers:

A failure, the need for vast quantities of clean water. To flush and wash the commercial solar cells.

A success, the ability to bring portable power to remote and off grid areas. Where only a small gas generator was possible before. Simplifies and eases the load while going to such areas. No need for gasoline.

A success, the use of solar power, as a direct water heat source, has been proven to decrease the need for normal means of home water heating.

A failure, the stable ability to bring a home under total solar power. By available area of panels, storage ability and days when less sun available cuts power.

A failure, the high maintenance, low output, and short life of panels.

A success, the decreased use and waste of small batteries for small electric powered hand devices. Like radios, calculators, over the life and use of the device.etc….
